Also, I have an Omega D2...but that doesn't matter. I do not see how the negative carrier shown in the lower left could possibly work for 645 format on 120 film. It is clearly oriented the wrong way. Obviously, it is for 645 format on 127 film.

Do you cut your 120 negatives into individual frames? or, have you removed the film strip guide pins? How does the film strp not get pinched in the pins - which are far to close together to allow a 120 strip between them....
